5. Pilot Province Nam Dinh
Since 1996: qp, n GWL decrease 0.4 to 0.7 m/year
Status:
High quality groundwater resources in South Nam Dinh are a rare and finite water reserve
Ongoing overexploitation of high quality groundwater leads to accelerating GW level decrease and intrusion of saline water
-7 m
-8,3 m
-7,9 m
-9,4 m

6. Pilot Province Nam Dinh
Major Achievements:
Installation of a GW monitoring network complementing national monitoring wells
Application of quantitative hydrogeo logical methods, GW monitoring
Design of structural / numerical model
Identification of information gaps, relevant for management decisions (GW extraction rates, GW recharge) SW NE
Sea

7. Pilot Province Nam Dinh
GW Chemical Composition:
High salinity groundwater widely distributes in qh, qp and n aquifers
Fresh water distributes in qp, n and t1 aquifers
Significant hydrochemical zonation in qp unit:
(I) Red River area: high saline water of Na-Cl dominated composition
(II) West and South areas: low saline water of Na-Mg-HCO3 dominated composition
The recharge of fresh water in qp most likely originates from the Western Triassic formations

8. Pilot Province Nam Dinh
Challenges in Groundwater (GW) Management:
Controlling GW Extraction
Registration and controlling extraction wells & licenses
Optimizing & Reducing GW Extraction
Identification of GW loss and misuse
Identification of alternatives wherever possible
Development of a GW Monitoring & Action Plan
Funding, technical expertise
Data management, …

9. Summary and Conclusion
Calculation of renewable and available groundwater resources requires reliable water use and extraction data
Ongoing overexploitation of high quality groundwater speeds up GW level decrease and saline water intrusion
Controlling GW extraction is crucial for a sustainable groundwater management
Continuous monitoring and setup of a Groundwater-Information System is crucial for assessing groundwater resources and thereby devising GW management recommendations
